Magnetic properties of materials
Question

The susceptibility of magnesium at 300K is  1.2×105. The temp is  800×tK, the susceptibility is  1.8×105. Then the value of 't' is
 

Moderate
Solution

As per Curie's Law , χ=CT χ1χ2=T2T1

T2=T1χ1χ2 T2=3001.2×1051.8×105

T2=300×1218 T2=800×t.K=200K

t=14=0.25
